To all 'whom t may concern.'

Be it known that I, ELBERT Gr. GHANDLEN, a citizen of the United States, and a resil ldent of Portland,v county of Multnomah, and

. ments.

`State of Gregon, have invented a new and usefullmprovement in Logging-Trucks, of which thefollowing is a specification.

The object of my invention is to provide a loggingk truck having a frame and pedestal construction affording great strength7 vso as to be adapted Vfor withstanding, without undue wear fand tear, the abusev to which logging trucks are subjected in logging service. InthisI respect I have particularly in mind the making of the ends of the truck of such construction as to be adapted to withstand the blows which in service are frequently delivered by logs against the sides of the trucks and by which, in the priorconstruction, the ends of the trucks were thrown out of alinement, causing the displacement of the transverse end sills carrying the coupling elements, and throwing the latter out ofjalinementto such extent that the truck was ,unfit for further yservice until repaired.

,` It is furtherl my object 'to obtain such result by a construction which will not increasethecost of manufacture over the common logging truck, but instead, tend to chleapen the cost. Y

lf attain my object byl making my truck frame and the pedestals of a constructionv substantially solid, embodying the following predominant features The frame of the truck is maderof solid,

yor one-piece sides,. preferably consisting of I-beams, having kspaces cut out near the ends Y f for the coupling; and

for inserting pedestals.V The kpedestals are spaces7 and for 'being rigidly fastened in place.

provide 4a-solid support on which to mount the end frame-members,' and coupling ele-V kThe details of the above described features .of my invention and 'other incidental f eatures are illustrated= in the accompanying `drawings in which Figure lis a -sideelevation of my truck, inthe jleft end of which is shown the pedestalsand journal-box,- but the near pedestal Furthermore the solid sides are jmadeof such length as t0 project a substantial distance beyond the pedestals, and thus Fig. 2 4is an end View of mytruck, the.

My truck consists of twof solid or one-pi'ece sides a, preferably made of I-beams. Adjacent each end of the sides is cut out a recf tangular space or recess b, for inserting a pedestal-casting c; leaving however a vertical portion z' of the web of the side extending across the top of the space vor recess b.

The pedestals are made with transverse inwith marginal portions or flanges c, adapted Vlower plates fw and fw', on which are mountfor overlying the web-portions f encompassing the spaces Z2, of the sides. The pedestal casting is provided atthe top with a marginal portion or flange g', and a com panion fiange h, spaced from the flange g so as to permit the vertical side extending across the space or recess b to be seated in the groove so formed, and cause said flanges gand h to overlie the web-portion z' of the side, and Apermit the overlying parts to be firmly fastened together by a rivet m or other fastening element. The pedestals are further provided at the top with laterally projecting portions y', j constituting a domeilike housing for the upper end ofthe springs v-lato bear in, the lower ends of said springs lbeing seated on the journal-boxfl, which is of the usual construction. Y

' vI prefer to fasten the pedestal casting c in place' by means of rivets as shown at m in Fig. 6 thereby avoiding the undesirable eifects of bolts becoming stretched, and the nuts of the bolts working off.

The sides a and a of the frame are made of such lengths that their ends n and a project asubstantial distance beyond the spaces or recesses b; and on said projecting ends are mounted the transverseendk bars, or

sills, 0 and o connecting the sides.

Thus theends of the solid I-beams'projec'ting beyond the journal boxes provide a solid support for the transverse end-sills capable of resisting the blows which are delivered in service against said projecting ends, and thus preventing the displacement of said end-sills and the throwing out of alinement of the coupling elements carried by the latter.

Between the sides a and a are fastened transverse frame members 1' and r', carrying the draft sills s and s. On the draft sills s and s are mounted channel bars t and t fastened to the end of sill o by a bent plate u.' The opposite ends of the draft sills s and s are connected to the end sill o by a bent plate 02.

. Between the channel bars t and t is carried the upperfcoupling element p, and, at

'the opposite end, between the draft sills s and s is carried the lower coupling element 17'; 'Each of the coupling elements comprises guides v and fv, a detail of one of` 'which is showninFig. 13. The guides for the lower coupling element 79 are fastened to the inner sides of the draft sills s and s', as shown in Fig. 9, and those for the upper coupling element p are fastened to the inner sides of the channel bars t and t', as illustrated in Fig. 11.

In the guides il' and 'v' are supported foled the coupler yoke a', of the 'coupler bar y. In the coupling yoke m is contained 'a spring s. These parts are of the same construction atl each end of the truck, and therefore have been designated by the same reference letters. j

Parts not described yhave no direct bearing on my invention, and may be of the usual,

to resist bending due to blows delivered 7 against them tol'therebyl prevent they displacement of said end-sillsV and throwing out of alinement of the coupling elements.

2. In a loggingtruck, the combination of sides each consisting of a one piece metal flanged beam, said beam beingrecessed near both ends to receive pedestals, the ends of the sides extending a substantial distance beyond Ysaid pedestalV recesses,` transverse end-sills secured upon the flanges of the similar end extensions of the respective sides and bracing said extensions withvrespect Vto each other, and coupling elements carried by vthe end-sills, the said end-sills preventing l,

displacement of the extended ends of the sides under blows delivered against them to thus prevent the throwing outv of alineinent Vof the coupling members.

3. Inr a truck, in combination withside members having web portions provided with a rectangular recess at each endfpedestals seatedand secured in said recesse`s,`eachfof said pedestals consisting of a casting comprising horizontal and vertical Hanges adapted to overlie the marginal web por` tions encompassing said recess, and transverse parallel inner vertical ianges spaced apart and projecting a substantial distance beyond the side faces of the pedestals, thereby providing journal box bearingsiand having a domelilre housing integral with the top porti'onsof saidY transverse Hanges for receiving the upper end of a springf Li. In a truck, in combination withside a rectangular recess at ,each end, pedestals seated; and secured in said recesses, each of said pedestals consisting of a casting comprising horizontal and vertical flanges Vmembers having web portions provided with adapted to overlie the marginal web por tions encompassing said recess, and a companion fiange spaced from, and parallel with the horizontal or top fiangeof the pedestal, said topV and companion flanges forming a groove in which to Seat the web portions of the sides at said recesses.

5. In a truck, in combination withv side members having web portions provided with a rectangular recess at each end7 pedestals seated and secured in said recesses, each of said pedestals consisting of a casting comprising horizontal and vertical flanges adapted to overlie the marginal Web portions encompassing said recess, and a companion flange spaced from, and parallel With the horizontal or top flange of the pedestal, said top and companion flanges forming a groove in which to seat the Web portions of the sides at said recesses, and said pedestals comprising further transverse parallel inner vertical flanges spaced ,apartand projecting a substantial distance beyond the side faces of the pedestals, thereby providing journal box bearings, and having a dome like hous ing integral with the top portions of said transverse flanges for receiving the upper end of a spring.

6. A pedestal consisting of a casting comprising lateral horizontally and vertically extending flange, a companion flange spaced from,' and parallel With the horizontal flange, transverse parallel inner vertical flanges spaced apart and projecting a substantial distance beyond the' face of the pedestal to provide a journal-box bearing, and a dome-like housingintegral With the top portions of said transverse flanges for lreceiving the upper end of a spring.
